We have teamed up to offer a family membership for $55 instead of $70 on Thursday, June 5. All you need to do is ask for the "Go Ask Mom 5" special at the museum box office or museum stores or enter the code GOASKMOM5 when purchasing a family membership online. Again, this is good only on Thursday, June 5!

The annual membership will get you in free for the whole run of Rainforest Adventure, a fun exhibit for kids ages 3 to 12 and their adults, plus you'll get free admission to the museum's next big exhibit, The World's Largest Dinosaurs, when it opens in October.

In addition to free admission to the museum's special exhibits, members can take advantage of discounts on birthday parties; discounts and priority registration for summer camps (which I highly recommend); a discount at the museum store; special events for members; and hospitality areas at some of the museum's big events such as BugFest.

The membership also gets you free or discounted membership to more than 300 science museums around the world, a great perk especially if you're traveling this summer.
